2013 Jaguar XFR: 510 hp, $84,095
If you look closely at this list, you’ll find something interesting the Jaguar XFR makes roughly the same power as the Mercedes-Benz E63 AMG, but costs $6610 less. What can you do with all that money? Buy some options, that’s what: an XFR with the “Speed Pack” (which adds an aero kit and ups the top speed to 174 mph), premium seats/headliner trim, and a heated windshield still costs less than the Mercedes. Even without the optional speed pack, however, the XFR is definitely quick: its 5.0-liter supercharged V-8 engine churns out 510 hp. That power is sent to the rear wheels through an eight-speed automatic transmission.
2013 Mercedes-Benz E63 AMG: 518 hp, $90,705
Despite being badged as an “E63 AMG,” the hopped-up Merc doesn’t have a 6.3-liter powerplant. Instead, it uses Mercedes-Benz’s twin-turbocharged 5.5-liter V-8 engine, which makes 518 hp. That power goes to the rear wheels through a 7G-TRONIC automatic transmission. The car is limited to 155 mph, but Mercedes is happy to sell true speed freaks a performance package that ups the power output to 550 hp and 590 lb-ft, tweaks the suspension, and resets the speed limiter to 186 mph. That performance pack isn’t cheap, though: it’ll run you $7300.
2013 BMW M5: 560 hp, $92,395
The BMW M5 might cost more than the Mercedes-Benz E63 AMG, but it also delivers more power. The M5′s 4.4-liter twin-turbo V-8 makes 560 horsepower without any performance packages or extra tuning, and it sends that power through either a seven-speed dual-clutch transmission or a six-speed manual transmission (U.S.-market only). It does earn a slap on the wrist, however, because it’s the only car on this list to use digital engine noise synthesizers, which amplify the engine note through the car’s speakers.
